John Hassall Howard, whose name does not appear on any official list, claimed to have emigrated with his wife and family as members of Thornhill's party, and was discharged from Thornhill's service in 1821 when he injured his right hand (Cape Archives CO 158,142). In a letter to the Colonial Department before emigrating, he described himself as a chemist, druggist and apothecary. It is not known how he was connected with William Howard, or whether he sailed in the Zoroaster in place of some other settler.
